The reaction mechanism of the photocatalytic oxidation of 2-ethoxyethanol (Ethyl Cellosolve, EtOCH<SUB>2</SUB>CH<SUB>2</SUB>OH) on TiO<SUB>2</SUB> powder was investigated by gas chromatography-mass spectrometry (GC-MS), infrared (IR) spectroscopy, and electron spin resonance (ESR) with spin trapping technique. Irradiation of TiO<SUB>2</SUB> powder with UV light in the presence of EtOCH<SUB>2</SUB>CH<SUB>2</SUB>OH under air led to the formation of ethyl formate, ethanol, acetaldehyde and carbon dioxide. The main product, ethyl formate was different from the product through the reaction pathway proposed before for primary alcohols. It was also different from the product of electrolysis on Pt. Reaction mechanism is proposed based on IR and ESR studies.
